Comment: At first sight, I thought this to be a tourmaline! But it is a very rare minty to olive green that I can not remember having seen ever in a sapphire. At times there is a metallic silvery glimmer to it (main photo), at times a fresh earthy grass hue (hand shot). Always a surprise when you look at it in different lights. Addictive lucid crystal under the lens and no inclusions. Big face, no window. Certified unheated sapphire over 2 carats. An astounding discovery even for the seasoned collector. Set in white gold, you will have an eternity of uniqueness to admire.
